Title: A Tale of Two Spirals

Abstract: Control of cell shape is a fundamental property of life, essential to the form and function of all organisms. Cell shape is governed primarily by an internal scaffolding structure called the cytoskeleton. Unlike human-made scaffolding structures, the cytoskeleton is highly dynamic and is able to change its configuration in response to developmental and environmental signals, allowing cells to adapt to changing conditions. My lab is interested in the molecular mechanisms that create, maintain and change microtubule architecture to meet cellular needs. In my talk, I will focus on how the Arabidopsis SPIRAL1 and SPIRAL2 proteins regulate microtubule tip dynamics and how these activities affect microtubule organization and cell shape.
